2 Product description
2.1 Design
The DIT 01 tank contents indicator consists of an electronic
pressure sensor and a microprocessor-controlled indication system contained in a sturdy plastic housing. The measured values
are shown on a 4-digit liquid crystal display (LCD). The function
key F allows you to switch on the device and select the display
modes litres, cubic metres, percentage and filling level. The
device is programmed via the two keys
and
A 3.6 V lithium
battery is contained in the housing of the tank contents indicator.
Under normal conditions (F key is pressed once a month), the
battery will have a service life of approx. 8 years. The battery is
not connected when the device is shipped. Prior to commissioning, the battery plug must be connected to the printed circuit
board.
The tank contents indicator comes with a 5 m long cable. The
free end of the cable is connected to the pressure sensor. The
pressure sensor and the tank contents indicator form one unit.
The pressure sensor is placed in the tank from the top and is
mounted either with a PG connection or a Euroflex combination
withdrawal fitting and sealed.
The pressure sensor includes a spacer so that the measuring
hole of the pressure sensor remains above the oil sludge level.
Different screw connections are shipped with the pressure sensor which are used to mount the pressure sensor cable to the
tank and seal it.

2.3 Function
The pressure sensor is located at the lowest point of the heating
oil tank and transforms the hydrostatic pressure of the heating oil
into an electrical signal. The measuring signal is transmitted to
the tank contents indicator via the cable. The electronic system
of the tank contents indicator uses this signal to calculate the
tank contents, which it displays in litres, cubic metres, percentage or filling level. The display mode is selected by means of the
F function key. The tank data is entered via the two programming
keys.

3.2 Installation and commissioning
Wall holder:
Use the enclosed screw (4 x 30 mm) and, if necessary, a dowel
(6mm) to mount the wall holder for the DIT 01 tank contents indicator at the desired location.
Moisture-proof
Use the enclosed screws and, if necessary, dowels, to mount the
junction box:
moisture-proof junction box for connecting the pressure sensor
cable and the cable of the tank contents indicator at the desired
location. Make sure to provide sufficient cable length. The tank
contents indicator must be able to be removed from the wall
holder, e.g. if you need to replace the battery.
Place the tank contents indicator into the wall holder and route
the cable into the moisture-proof junction box.
Push the connection elements required for the tank connection
(PG connection, screw connection or Euroflex) onto the pressure
sensor cable in the correct sequence and orientation.
Cable connection:
Route the cable of the pressure sensor to the moisture-proof
junction box and connect the two cables by means of the insulating screw joint. Make sure to connect the wires of the same
colour, respectively. A transparent tube can be seen at the cable
end of the pressure sensor. This tube provides the pressure sensor with atmospheric pressure. Make sure not to close or bend
this tube. The moisture-proof junction box should not be completely tight in order to avoid incorrect measurements.

After you have electrically connected the pressure sensor and
the tank contents indicator, open the housing of the tank contents indicator by turning the upper part of the housing all the
way to the stop and pulling it up.
Plug the 2-pole battery plug into the 2-pole socket on the printed
circuit board.
Close the housing of the tank contents indicator by pushing the
two housing parts together. Since the battery was connected, the
tank contents indicator was switched on. When the battery is
connected for the first time, the zero balancing function is started
once. The display switches between "Zero" and the current offset
of the pressure sensor (indication in hPa = mbar). The top left
corner of the display shows the arrows
. to indicate that you
are in calibration mode. By pressing the
and
keys simultaneously, you correct the offset to the value 0.00.
When you do this, the pressure sensor must not be in the
tank! In this state, you can zero the system any number of
times. Press the F key in order to exit the zero balancing mode.
An arrow is shown at the bottom of the display pointing to the
unit Litres
After you have zeroed the unit, install the pressure sensor in the
tank. Insert the probe head into the tank from the top. Fixate
the cable in the screw connection in such a way that the probe
tip just reaches the tank bottom. The measuring hole of the pressure sensor must not be immersed in the oil sludge. The oil volume below the level of the measuring hole is not detected by the
pressure sensor! Seal the PG connection or the Euroflex in the
tank cover to make the connection smell-tight and tighten the PG
connection to prevent the cable from moving
Different options are available for mounting the pressure sensor
in the tank::
1) In combination with the Euroflex withdrawal fitting:
Lower the pressure sensor into the tank Move the cable
in the Euroflex withdrawal fitting until the probe tip just reaches the tank bottom. The measuring hole of the pressure sensor must not be immersed in the oil sludge. After having
adjusted the correct cable length, tightly screw the black plastic screw (pressure screw) into the body of the Euroflex fitting.
This applies pressure to the two O rings between the cable
and the body of the Euroflex fitting, fixates the cable and
assures a pressure-tight connection.

keys to set the previously determined total
volume of the tank facility. Press
to select the digit to be modified. Press
to change the selected digit in the range from 0 to
9 Volumes of up to 9999 litres are entered without a comma
digit. Volumes greater than 9999 litres are entered as cubicmetres (1000 litres = 1 cubicmetre) with a comma digit. Press
to move the comma digit. Press the F key to confirm the volume
setting and continue with the tank height data.
3. Tank height:
The arrow at the bottom of the display points to the unit
Percentage. The display shows the currently selected tank
height. If the display shows 0000 this means that no tank height
has yet been entered. Use the
and
keys to set the previously determined tank height. Press
to select the digit to be
modified. Press
to change the selected digit in the range from
0 to 9. Press the F key to confirm the volume setting and continue with the current filling level data.
4. Current filling level:
The arrow at the bottom of the display points to the unit Filling
Level (FH). The display shows the filling level currently measured by the probe. If you measure heating oil, the reading should
be pretty close to the actual filling level. If you need a greater
accuracy, enter the previously determined filling level. Please
note: the fuller the heating oil tank, the greater the accuracy. The
maximum accuracy is obtained if the tank is completely full. At
levels of less than 50%, a correction of the value indicated is not
meaningful. In order to correct the current filling level, you can
overwrite the displayed value. Use the
and
keys to set the
previously determined filling level. Press
to select the digit to
be modified. Press
to change the selected digit in the range
from 0 to 9. Press the F key to confirm the filling level setting.
